Description

Technical Field

[0002] Building water supply and drainage include building water supply and building drainage. Building water supply refers to the process of introducing water from urban water supply network or self-supplied water supply network into the room and sending it to domestic, production and fire-fighting water equipment through distribution pipes. Building drainage is the discharge of sewage from residential buildings, public buildings and production buildings. When the sewage inside the building is discharged from the pipe, anti-blocking devices are required to reduce and prevent the blockage of the drainage pipe caused by some domestic garbage.

[0003] Chinese patent number CN217811455U discloses an anti-blocking device for building water supply and drainage. The device is provided with a connecting pipe on the side of the drain pipe. When sewage is discharged from the drain pipe, the debris is blocked by the filter plate and slides into the connecting pipe and is collected by the collecting pipe. The device has a simple structure and strong practicality. The debris is discharged into the connecting pipe to prevent blockage inside the drain pipe. The collecting pipe can collect the debris for easy cleaning. However, the filter plate in the device is fixed and inconvenient to disassemble. As time goes by, the impurities on the filter holes in the filter plate will increase, and eventually the filter plate will be easily blocked, affecting drainage. For this reason, we provide an anti-blocking device for building water supply and drainage. Utility Model Content
